“…It is based on the application of the Onishchik's modified formula proposed in 1937. The strength of masonry depends on the strength of brick as well as compression and bending strength of mortar that are determined by destructive methods [25][26][27].…”

“…The use of non-destructive methods reduces the accuracy of the test, so it is difficult to make a reasonable decision about the reserve of load-bearing capacity of masonry [25,[29][30][31]. The development of these methods seems to be effective in combination with destructive methods.…”

The reliability of structures in the reconstruction of buildings depends on quality control methods that can be destructive and non-destructive. Directions for improving the accuracy of methods for assessing masonry as a complete construction system are proposed in the paper. The factors to be taken into account when assessing the bearing capacity of the operating buildings have been stated. Margin of errors of a number of parameters using different methods of strength assessment have been determined.

“…So far, it is often not possible to relate and interpret these measurements with regard to strength and stiffness properties required for the design and evaluation of reliability of the structure with sufficient certainty. Advanced methods for the assessment and probabilistic evaluation of existing structures make use of updated information and are already successfully applied in different other fields [51] but are still scarce in masonry engineering [29,[52][53][54][55][56].…”

Methods for the Assessment of Critical Properties in Existing Masonry Structures under Seismic Loads—The ARES Project

Masonry structures are notoriously vulnerable to horizontal actions caused by earthquakes. Given the high seismicity of the European region, and that the European building stock comprises a lot of masonry buildings, knowledge about their structural response to seismic excitation is particularly important, but at the same time difficult to determine, due to the heterogenous nature of materials and/or constructional techniques in use. An additional issue is represented by the current methods for mechanical properties assessment, that do not provide a reliable framework for accurate structural estimations of existing buildings characterized by different typological properties. Every structure, in other words, should be separately inspected in regard to its mechanical behaviour, based on dedicated approaches able to capture potential critical issues. In this review paper, an insight on the Croatian ARES project is presented (Assessment and Rehabilitation of Existing Structures), including a state-of-the-art of the actual building stock and giving evidence of major difficulties concerning the assessment of existing structures. The most commonly used techniques and tools are compared, with a focus on their basic features and field of application. A brief overview of prevailing structural behaviours and Finite Element numerical modelling issues are also mentioned. As shown, the general tendency is to ensure “sustainable” and energy-efficient building systems. The latter, however, seem in disagreement with basic principles of structural maintenance and renovation. The aim of the ongoing ARES project, in this context, is to improve the current knowledge regarding the assessment and strengthening of structures, with a focus on a more reliable design and maintenance process for existing masonry buildings.

“…Figyelembe kell venni, hogy minden módszernek vannak korlátai az anyag természete és geometriája, a vizsgálati terület és a vizsgálat által lehetővé tett alkalmazási sebesség miatt [1]. A technológia fejlődésével nem csupán a fémfelületek és hegesztési varratok penetrációját lehet elvégezni ilyen technikával, hanem például szálerősítéses kompozitok [2], és akár még épületek [3] és betonszerkezetek [4] esetében is alkalmazható.…”

A roncsolásmentes vizsgálatok napjaink egyik legfontosabb vizsgálati eljárásai közé tartoznak. Egyik legnagyobb előnyük a többi vizsgálathoz képest, hogy folyamatos üzemelés közben is lehetőségünk nyílik a vizsgálat elvégzésére anélkül, hogy magát az folytonos üzemelést megszakítanánk. Jelen tanulmányban a folyadékbehatolásos, más néven penetrációs vizsgálatokkal végzett kísérletek eredményeit, és a hibák összehasonlítására szolgáló számítógépes eljárást mutatjuk be.
